Amendment #1 addresses vendor questions. Answers are in ORANGE, below.

Q1. WET WELL DIMENSIONS AND SURFACE AREA

A1: KL Main LS has a diameter of 105 inches with a depth of 180 inches, Back bay dia. 80" and depth of 126", Temple Bar dia. 75", depth of 213"

Q2. SEWAGE FLOW RATES FOR BYPASS PUMPING

Can NPS provide expected average and peak sewage flow rates (gpm) for each of the three lift stations so that bypass pumping equipment can be sized appropriately?

A2: Historic flow rate maximums for Temple Bar= 7,000 gpd, Katherine Main= 15,129 gpd, KL Back bay= 1,700 gpd

Q3. TEMPLE BAR LINER REMOVAL AND SUBSTRATE CONDITION

For the Temple Bar wet well, can NPS provide the approximate square footage of failing fiberglass liner that must be removed, along with the estimated condition and depth of any spalling or structural damage to the underlying concrete substrate? Has any prior condition assessment, inspection report, or as-built drawing been completed that can be shared with offerors?

A3: Unknown, Operators can see the failing liner from the hatch on top of the wet well. No further inspection has been conducted.

Q4. SURFACE PREPARATION STANDARD AND COATING THICKNESS

What is the required minimum dry film thickness (DFT) for the protective coating, and is surface preparation specified to a particular NACE or SSPC standard (e.g., SSPC-SP 6, SSPC-SP 10) with a defined blast profile?

A4: Surface must be cleaned of all grease , oil, rust, scale and other contaminants in accordance with ICRI Technical Guidelines No. 03732. 200 mils thickness per coat, additional coats may be needed in certain instances.

AMENDMENT #1 4-29-26

Q5. BYPASS ROUTING DISTANCE AND DISCHARGE TIE-IN POINTS

What is the approximate distance and elevation change for the bypass routing (Back Bay to Main at Katherine Landing, and Main lift to the sewage lagoons via force main at both sites)? Are there existing force main connection points or manholes that the contractor can tie into for bypass discharge, or must the contractor provide all temporary piping?

A5: No existing tie in points on force main. Depending on tech approach to project the distances can vary. The force main should be able to be tied in to within a 100' radius at all locations.
